•    Bipolar depression and major depressive episodes in major depressive disorder: where you ay feel sad all the time or you may find that you feel depressed, feel guilty, lack energy, lose your appetite or can't sleep.

When Atrolak XL is being taken to treat major depressive episodes in major depressive disorder, it will be taken in addition to another drug being used to treat this illness.

Your doctor may continue to prescribe Atrolak XL even when you are feeling better.

-    You have had a stroke, especially if you are elderly.

-    You have problems with your liver.

-    You have ever had a fit (seizure).

-    You know that you have had low levels of white blood cells in the past (which may or may not have been caused by other medicines).

-    You have diabetes or have a risk of getting diabetes. If you do, your doctor may check your blood sugar levels while you are taking Atrolak XL.

-    You or someone else in your family has a history of blood clots, as medicines like these have been associated with formation of blood clots.

Tell your doctor    immediately if you


-    Fever, severe muscle stiffness, sweating or a

lowered level of consciousness (a disorder called “neuroleptic    malignant syndrome”).

Immediate medical treatment may be needed.

-    Uncontrollable movements, mainly of your face or tongue.

Thoughts of suicide and worsening of your depression

If you are depressed you may sometimes have thoughts of harming or killing yourself. These may be increased when first starting treatment, since these medicines all take time to work, usually about two weeks but sometimes longer. These thoughts may also be increased if you suddenly stop taking your medication. You may be more likely to think like this if you are a young adult. Information from clinical trials has shown an increased risk of suicidal thoughts and/or suicidal behaviour in young adults aged less than 25 years with depression.

If you have thoughts of harming or killing yourself at any time, contact your doctor or go to a hospital straight away. You may find it helpful to tell a relative or close friend that you are depressed, and ask them to read this leaflet. You might ask them to tell you if they think your depression is getting worse, or if they are worried about changes in your behaviour.
